How does photographer ps fix the picture to make it longer?

The easiest way for a photographer to lengthen a picture in ps retouching is to open "Image-Image Size" and click to remove the lock (arrow) that locks the aspect ratio, so that the value of width or height can be changed separately. After confirmation, the picture can be stretched accurately.

I hope to adopt.
